When faced with a difficult task, the first decision is whether or not
to commit -- to take on the task with the intent to succeed, or to quit
before you even begin

If one decides to commit, having to grind through some tough spots
becomes inevitable. When that happens, it's time to really just Suck it
Up and push through (sensibly -- not to exhaustion, always living to
fight another day).

One thing that one should not do however, is to stay mum about how
difficult the task is. Shutting up is probably the fastest way to
insanity -- we need an emotional outlet.

So, when faced with tough spots, talk about it. To your spouse, to your
coworkers, to your cat, to your reflection, whatever... This is not to
tell the world, but to tell yourself.

Once the complaints have been heard, and courage rises, facing that
tough spot somehow becomes a matter of course.
